Impella CP vs. IABP — Impella CP showed significantly lower 180-day mortality
Describe the CD4 threshold at which PCP prophylaxis should be initiated in HIV patients, the first-line agent, and the alternative in sulfa allergy.
CD4 <200 cells/μL; TMP-SMX; dapsone or atovaquone in sulfa allergy
Name the four criteria of the CURB-65 score, the threshold that mandates inpatient admission. Answer atleast 3/4.
CURB-65: Confusion, Urea >7 mmol/L, RR ≥30, BP <90/60, age ≥65. Score ≥2 = inpatient; ≥3 = ICU consideration.
After large-volume paracentesis (>5L) in a cirrhotic patient, what post-procedure intervention is recommended to prevent paracentesis-induced circulatory dysfunction (PICD), and at what dose?
IV albumin 6–8 g per liter of ascites removed
This FDA-approved (2023) drug is used for the acute termination of paroxysmal supraventricular tachycardia (PSVT) without IV access. Name the drug, MOA, and ROA. Answer all three.
